Ship project history: Technical project on designing of seaworthy torpedo boat has been made by Austro-Hungarian
Navy early 1910. Basic requirements were: 500-550t displacement,
steam turbines as main engines, 30kts speed with possibility of running
at this speed within 16hrs, 4 single 66mm guns and 3 450mm TTs. In June, 1910
there were presented three projects from STT, Hanz Danubius and CNT. All of them were similar enough among themselves and mismatched the shown requirements:
250t displacement, 28kts speed within 10hrs, 2 66mm/30 Škoda guns and 3 single or 2
twin 450mm TTs. With a view of economy Naval HQ agreed on displacement reduction, but stored the requirement of 30kts
speed. Further coordination lasted more than a year, but finally seamen had to agree on reduction of
speed to 28kts. Nevertheless, torpedo boats were characterised as exclusively successful and
were built by largest class for Austro-Hungary (27 ships), including three groups. 16/1/1912 STT
received order for 8 ships (74T-81T; letter T means "Trieste"), in February, 1913 16
ships (82F - 97F; "F" means "Fiume")
were ordered to Hanz Danubius, building was conducted in
Fiume and Porto Ré; 5/7/1913 CNT
received an order on 3 ships (98M-100M; "M" means "Monfalcone"). At
division of former Austro-Hungarian fleet in 1920 8 torpedo boats were transferred
to Yugoslavia, 7 to Romania, on 6 to Greece and Portugal. Yugoslavia received 4
boats of 1st and 4 boats of 2nd series. They had relative
data, but significantly differed on appearance, in particular, first were one-funneled, and second had
two funnels. The forecastle on 1st series was a little above, that ensured with better seaworthiness. Bow TT placed between forecastle
break and bridge. The rated power was 5000hp, maximally ships of 1st group reached
up to 5700hp, and 2nd up to 6000hp. On trials all torpedo boats exceeded contract
speed, but to the Second World War beginning they reached about 20kts.

Naval service: T4 (ex-79T) was stricken in 1932 after wrecking. Survived boats in April, 1941
were captured by Italian troops and commissioned by Italian Navy under former numbers. T1 in
late 1943 was returned to Yugoslavian Government in exile, and since 1945 were
commissioned by new Navy of Yugoslavian Republic as Golesnica.T3 in September, 1943
was captured by Germans and commissioned by Kriegsmarine as TA48,
she was lost 20/2/1945.
